SMOKE AND GAS CONSUMER FOR LOGOMOTIVES.

Specification of Letters Patent.

Patented Jan. 9, 1912.

Application filed JanuaryvlG, 1911. Serial No. 602,755.

To all whom it may concern:

Be it known that I, DANIEL GOFF, a citizen of the United States, residing at Millville, in the county of Cumberland, State of 5 New Jersey, have invented a new and useful Smoke and Gas Consumer for Locomotives,

s ture shown 1n Fig. 4.

of which the following is a specification.

This invention relates to a new and useful induced draft and smoke consumer for boilers and more particularly to a consumer for use in connection with a locomotive type of boiler.

It has for an object to provide a construction whereby steam and air may be introduced in suitable quantities into the fire box at an advantageous point to cause a more complete combustion of the fuel products and serve as an efficient draft producing means. The vintroduction of the steam and air is regulated by a suitable apparatus which may be controlled either manually or automatically, wherebythe quantities of the mixture maybe proportioned' properly to' produce the desired combustion.

It further consists of other novel featuresA of construction, all as `will be hereinafter fully set forth.

For the purpose of illustrating my invention I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same will be found in practice to give satisfactory and' reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Certain features shown herein are embodied iny my application, No. 590,850, filed November 5th, 1910, and no claims are here vmade for such features as are claimed in the m-x, Fig. 1. Fig. 3 represents a detail, partly in section, of the steam super-heater box. Fig. et represents an end elevation showing the automatic cont-rol for the auxiliary steam supplying device. Figs. 5 and 6 represent sectional details of a valve struc- Similar numerals of reference indicate corresponding parts in the figures.

1 designates a tire box of a locomotive ltype of boiler, the same being formed in the usual manner by the inner shell 2 and the outer shell 3, said shells forming between them the usual water leg 4.

5 .designates a plurality of grate bars forming the grate proper at the lower portion of the re box, said grate bars being of any desired construction adapted to carry out the required functions. Air is passed through the grate bars 5, in the present instance, from the bottom of the tire box and preferably directed thereto by means of the open ended shield 6. This open ended shield 6 serves to direct a current of air beneath the grate when the locomotive is running and thereby produces the necessary draft to support combustion.

7 designates suitable conduits or pipes located beneath the grate `bar 5 and provided with perforations 8, adapted to discharge steam through said grate, thus mixing it Awith the air supplied from the shield 6.

These conduitsv 7 are connected by a pipe 9 to a suitable valve chamber 10, the latter serving herein as a receiver for steam supadjacent each of the collectors 14k and 15, be-

ing controlled by levers 17 extending into reach of the engineer, fireman or other operator. There are preferably two of these air supply pipes 13, one located at each side of the fire box and each terminating in a substantially horizontally disposed header 18 with which a plurality of discharge pipes 19 are connected, these latter passing through the water leg 4 and communicating with the interior of the fire box. Each of the pipes 19 has a steam nozzle 2O projecting therein and operating with the effect of an injector, by means of which steam is mixed with the entering air and aids in the complete combustion of the fuel. 'Ihese nozzles 20 are suitably connected with the steam supply pipe 21 leading from the valve chamber 10, the latter being a suitable control for admitting steam as desired.

22 designates a steam box, preferably disw` posed transversely of the fire box, in the present instance being secured to the rear Wall thereof and suitably positioned between and with respect to the stay bolts 23, as will be apparent by reference to Fig. 2.

24 designates a compartment formed within the box 23 by means of a partition 25 which forms, with the'box walls, a space or conduit 26, through which live steam is passed prior to entering the compartment 24. It will be noted that the box 22 is preferably provided with a plurality of caps 27, each having an opening 2S therein for the purpose of delivering steam outwardly into the fire box. In order to regulate the discharge of steam from the compartment 24, I preferably employ both a manual and an automatic mechanism for the purpose, the same consisting, as herein disclosed, of a steam chest 29, receiving steam from the pipe 30, which is preferably supplied by suitable connection to the dry pipe 12. A branch pipe 31 having the valve 32 therein, leads from the pipe 30 to the passage 26 so that steam passes therethrough and is conveyed by a pipe 33 to one side of a pressure operated valve 34. The opposite side of the yvalve 34 communicates with a pipe 35 leading to the compartment 24, so that when the valve 34 is open steam has free access to the caps 27 and is discharged through the openings 28. The valve 34 is cont-rolled, in the' present instance, by an arm 36 suitably pivoted to a stationary part and connected to t-he stem 37 of the valve` 34 and having connection also by a rod 38 of the piston 39. The arm 36 is maintained-in normal position, in the present instance, through the medium of a spring 40, the operation of which will be readily understood. The piston 39 is located in a suitable cylinder 41 with which a pipe 42 communica-tes at a point below the said piston, so that the latter is raised by pressure as soon as steam is admitted by way of the pipe 42.

43 designates a suitable exhaust conduit for the cylinder 41. A valve 44 is preferably located in the pipe 42 for manual operation-thereof, if desired.

The pipe 42 communicates with the chest 29 and is opened and closed, in the present instance, by means of a slide valve 45, the same also governing the exhaust pipe 46, in

which latter a valve 47 is preferably located for a purpose to be hereinafter described.

43 designates a spring secured to the slide valve 45 and adapted to operate the valve in one direction, movement in the opposite direction being accomplished by the closing of the furnace door 49, it being noted that a link 50 and rod 51 form a suitable connection between the valve 45 and door 49. The construction just described permits the spring 48 to open the valve as soon as the furnace door has begun its opening movement, while the closing of the door draws the valve to closed position against the tension of the spring 48.

In the operation of t-he device, the steam normally passes through the pipe 31, passage way 26 of box 22 and pipe 33 to thel valve 34, from which it has no escape as long as the valve 34 is closed. As soon as the furnace door is opened to replenish the fire or the like, the valve 45 is shifted by the spring 48 to open the pipe 42 to the direct flow of steam from the supply pipe 30, the pressure thereof raising the piston 39 and operating the arm 36. Operation of the arm 36 causes the valve 34 to open and Vpermit steam to flow from pipe 33 by way of pipe 35 to the compartment 24 and thence be discharged through the openings 28. Closing of the furnace door 49 shifts the valve 45 and brings the pipe 42 into communication with the exhaust 46 so that the piston 39 is lowered and the valve 34 again closed. The function of the valve 47 in the exhaust 46 is to afford a means for retarding the return of the cylinder 39 so that a dash pot effect is produced which maintains the valve 34 open for a predetermined length of time.

For manual operation of the mechanism a bypass and valve 52 are positioned between the pipes 33 and 35 so that should it be. de sired to admit steam to the compartment 24 at a time when the furnace door is closed, it only becomes necessary to open this said valve 52, whereupon steam is shunted around the valve 34 and passes directly to the desired point.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice-to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: i
